  2. 1. On Quality in Radiotherapy Treatment Plan Optimisation

    Author : Hunor Benedek; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Pareto optimisation; Pareto fronts; Dose prediction; Machine learning; Deliverable treatment plans; Volumetric modulated arc therapy; IMRT; patient-specific plan quality; plan quality; Multi Criteria Optimisation; Automated Treatment Planning;

    Abstract : Radiotherapy is one of the essential treatments used in the fight against cancer. The goal of radiotherapy is to deliver a high dose of ionising radiation to the tumour volume and at the same time minimise the effect on healthy tissue by reducing the radiation to critical organs.

  4. 2. Slab track optimisation considering dynamic train–track interaction

    Author : Emil Aggestam; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modelling; Genetic algorithm; Slab track; Transition zones; Dynamic vehicle–track interaction; Optimisation; Measurement; Ballastless track;

    Abstract : Slab track is a type of railway track that is frequently used e.g. in high-speed applications as an alternative to ballasted track. Slab track is also well suited on bridges and in tunnels since no ballast is required and the cross-section of tunnels can be reduced. READ MORE

  5. 3. Modelling the Role of Nuclear Power and Variable Renewables in Climate Change Mitigation

    Author : Mariliis Lehtveer; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy system model; nuclear power; multi-criteria analysis; variable renewables; climate change; optimisation;

    Abstract : As the number of people on Earth and our energy needs have increased the system for providing this energy has become ever more complex and complicated and thus the need for more systematic understanding of it has grown. However, change in energy system is slow and many of the challenges that we face such as mitigating climate change need global solutions. READ MORE

  6. 4. A Simulation-Based Optimisation Method for PLC Systems

    Author : Bo Svensson; Bengt Lennartson; Rolf Bernhardt; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Simulation based optimisation; Virtual manufacturing; Industrial control system; PLC; Continuous simulation; Parameter tuning; Optimisation methods; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : Tuning of process parameters such as time constants, cam values, velocities and robot paths, in order to increase capacity utilisation, is today a challenging manual on-line task in many automated manufacturing systems. On-line methods interfere with production and will cause unwanted downtime, which indeed reduces capacity utilisation. READ MORE

  7. 5. Sparse Modeling of Harmonic Signals

    Author : Filip Elvander; Statistical Signal Processing Group; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; multi-pitch estimation; sparse modeling; convex optimisation; inharmonicity; sparse recursive least squares; adaptive signal processing; optimal transport distance;

    Abstract : This thesis considers sparse modeling and estimation of multi-pitch signals, i.e., signals whose frequency content can be described by superpositions of harmonic, or close-to-harmonic, structures, characterized by a set of fundamental frequencies. READ MORE
